4. INTRODUCTION
Warning: For trouble free operation of the boiler, and to be assured of the full guarantee, the following
items are required:
A. An automatic air and dirt separator must be installed in the installation and a strainer in
the return also devices as shown on pages 5 or 6.
B. Minimum static water pressure should be more than 0.5 bar.
C. The system is flushed, water tested and additive utilised if required.
D. Boiler auto air vent cap must be open and all system air vents open.
E. Low and high water cut out pressure switches ( usually in the fill unit) connected in the
Boiler volt free control circuit in series with other controls on terminals 13 - 14 or by 0 volt
when using external 0 to 10 volt control by others.
F. Control of Boiler on/off must never be by interruption of the mains supply.
G. When using a common flue the inbuilt cascade control must be used.
These instructions are written for the installer of Strebel products and contain all necessary information on
the installation and adjustment of S-CB boilers. We suggest that you read the instructions before installation
to ensure that all work is done correctly. We suggest that you keep these instructions near the boiler.
4.1 Operation of the S-CB Boiler
The heating boilers from the Strebel S-CB series are central heating boilers with maximum high efficiency.
Such performance is reached by, among other things, using a special heat exchanger made of stainless steel.
The heat exchanger allows flue gases to cool down below condensation point, condensing the flue gases and
releasing extra heat. This has an immediate positive impact on the efficiency, exceeding 100%net calorific.
•
S-CB flue gases have a low temperature (below 85°C), the boiler needs to have a high efficiency
approved stainless steel or plastic flue system .Aluminium flue systems are not allowed to be
connected to these boilers. Adequate drain points must be added to the flue system with a u trap.
4.2 Controls
The Strebel S-CB Boiler adjusts to the demand for heat by using flame modulation and external controls.
That is on the basis of 1) 0 to 10 volt control. 2) Strebel optimiser control 3) Built in weather compensation
with an outside detector. 4) RC or E-BUS .For RC or E-Bus system, see separate booklet.
The boiler control is equipped with:
Control for a DHW Cylinder with a diverter valve or a pump (pump via a relay both not supplied)
Connection for a Heating pump via a relay (pump and relay not supplied)
Connection for a room thermostat, on/off control, optimiser or 0 to 10 volt control (see 4.4.1).
4.3 Frost protection
Frost protection does not protect the system or system pumps. It protects the boiler.
Frost protect the system by fitting devices to link out any time controls. In a frost condition (at 7° Boiler
temperature) the Boiler internal pump starts. When the boiler water temperature falls down to 3°C, the burner
is also ignited. This operation will cease as soon as the boiler temperature has reached 10°C.
4.4 Cascade control
Using the integrated cascade control, a maximum of 8 boilers can be controlled in a cascade configuration.
The Cascade has in-built full logic step control. The Boiler will require a Flow temperature sensor and 2
wires to each boiler in a daisy chain. When using a common flue the cascade control must be used
4.4.1 0-10 VDC connection available
The boiler is equipped to take a 0-10 VDC signal from a controller by others (set at time of commissioning)
with which up to 8 boilers can be controlled in cascade, utilising the built in cascade manager. (0 Volt is
no heat demand.) The Boiler will require a Flow temperature sensor at extra cost.

After removing the carton, the easiest way to take the boiler off the pallet is as follows:
2.
Lift the pallet including the boiler (at the side of the flue outlet) to a vertical position.
3.
The boiler has a polystyrene block, which now supports the Boiler on the floor.
4.
Push the Boiler a little forward, until the pallet is not touching the floor anymore.
5.
The boiler stands now on the flow- and return pipes and the polystyrene block.
6.
Take away the pallet (See also 6.3).
The boiler can now be lifted (unclip and remove the Boiler door before lifting) easily for mounting, by
putting a hand at the lower side of the boiler.
Page 9 of 51
6.2 Select the position for the Boiler
Select a position in the building with adequate access to the front, side and the bottom of the boiler for future
maintenance and servicing. The boiler must have at least 20 mm space at each side.

Page 11 of 51
6.3 Mounting the Boiler
Prepare the Boiler for mounting as in 6.1.Determine the positions for the flow and return pipes using the
suspension bracket or a suspension frame, if any. When marking the holes, ensure that the suspension bracket
or frame is level. Drill the holes for the flow and return pipes if required then hook the heating boiler onto the
bracket or place it upon the frame.
6.4 Air supply & flue types
When using multiple SCB Boilers on a common flue the inbuilt cascade control must be used. SCB
Boilers 60kw to 100kw use a co-axial flue. Twin pipe flue-ing utilises an adaptor at extra cost .Boilers 120.
150 and 180 kw use parallel i.e. one air inlet tube and one exhaust tube a co-axial adaptor is available at
extra cost. . All Boilers can be used in a room sealed application or, if the boiler room or fitting space
complies with the relevant ventilation requirements Boilers can be non room sealed I.E. exhaust only,
Providing ventilation as per current regulations is in place. See pages 10 and 11 for flue connections.
Install the horizontal flue parts under 1% fall in the direction of the boiler (one centimetre for every
linear metre). Adequate drain points should be installed throughout long horizontal exhaust runs and
at the base of any vertical flue exhaust run. 60 mm (minimum ) “u” traps should be utilized.
6.5 The air inlet and flue gas outlet system.
The Boiler is ( normally )room sealed, the casing is airtight with air entering through the air supply
connection only. Always ensure the casing is placed over the boiler when the boiler is in operation! The
available pressure for the inlet and flue system is 250
kW
Pa, unless data from the table is being used.

N.B.! Install the horizontal flue parts under 1%
fall in the direction of the boiler (one centimetre
for every linear metre). Failing to do so may result
in water condensation building up in the flue gas
tube. In turn, this may cause failure.

The table on the left shows the relationship between
the Boiler output and the resistance of the air inlet
and flue. Up to a resistance of around 250 Pa the
output will be approximately the same as the Boiler
data plate In the event of a greater resistance ( up to
maximum 600 Pa ) this will change the Boiler output
. The resistance and the change of output only affect
the maximum output and not the minimum.
Tip! Remember that possible output changes may
influence hot water production and
transmission/absorption calculations.

25 Pa subtracted from 250 Pa leaves 225 Pa
Each metre length of 125/80 flue has a resistance of 8.5 Pa. 225 divided by 8.5 =26.4
Therefore the above example allows a straight flue run of 26.4 metres.
Reduce this flue run by 1 metre for each 90 degree bend or ½ metre for each 45 degree bend.
See also sample parallel flue calculation on page 16
Install horizontal Flue parts under 1% fall in the direction of the boiler (one centimetre for every
linear metre).

6.5.2 Single & Cascade resistance tables of air inlet and flue.
The output of the boiler is affected by the resistance of the air inlet and flue system (as a result of controlled
gas/air ratios in the Boiler). At a resistance up to 250 Pa, the output will be as indicated on the Boiler data
plate. Higher resistance of up to 600 Pa max can be overcome with reduced Boiler output (see page 12).
An under pressure, in the flue gas outlet, is not required, a positive pressure is created by the fan of the Boiler
which is specially designed for this purpose. As a result of this, the diameter of the common air inlet and flue
gas outlet is minimised; while the built in non return air valve prevents recirculation between the Boilers
when 2 or more are used on a common flue.
Table Resistance of the air inlet system
The stated Air inlet diameter is that used between the boilers and the roof or wall terminal.

6.8 Condense water drain
The condense water drain is next to the centre at the bottom of the boiler and has a ¾ inch hose discharge.
Connect this flexible hose to the drains via a tundish or oversize waste pipe. Also consider a waste trap.
N.B.!
Use only plastic parts with the condense water drain. Metal lines are not allowed.
Tip!
Blockage of this drain may cause damage to the boiler. The drain connection is correct when the condense
water can be seen flowing away, e.g. using a funnel. Any damage that may occur due to a blockage is not
covered by the warranty.
6.9 Central Heating
If plastic material for the flow and return from the radiators or under floor heating is being used and not
oxygen diffusion proof to DIN standard 4726/4729 a separation between the central heating water of the
boiler and the system will be required, e.g. using a plate heat exchanger. This will prevent contamination of
the boiler heat exchanger with magnetite. If the plastic material is not to the DIN standard failure to provide
such separation will void the warranty of any boiler parts relating to water.
6.9.1 Central Heating circuit
The S-CB has no pressure relief safety valve. This should be fitted in the flow of the system in close
proximity to the boiler (Boiler side of any valves). See pages 5 & 6.
The S-CB has no internal bypass. Low loss headers must be used to allow flow, even when all system valves
are closed.
Tip!
To prevent contamination of the S-CB heat exchanger, it is recommended to thoroughly flush the system
with clean running water prior to first use.
6.9.2 The expansion vessel
Please remember that the capacity of an expansion vessel is chosen or installed to match the capacity of the
central heating system and the static pressure. Fit the expansion vessel in the return of the central heating
system (see page 5 & 6 2.1 and 2.2) Expansion vessels and fill units available at extra cost from Strebel.
Page 17 of 51
6.9.3 Internal Pump
The pump has a speed regulator adjusted to the highest setting: Do not change this setting! The S -CB has a
built-in pump control with a standard 3-minute over run.
The pump will work at top speed when heat is required. When heat is no longer required, the pump will
continue to run for another 3 minutes. The pump and connected three-way valve for the calorifier or external
pump (if fitted) are also activated for one minute every 24 hours. The 24 hour cycle starts as soon as the
power supply to the boiler is activated.

7. INSTALLATION INSTRUCTIONS FOR THE ELECTRICIAN
7.1 Connecting to the mains power supply
The console has an ON / OFF button to switch the Boiler on or off.
The electrical connections to the S-CB are made via discreet plugs and sockets which are located within the
boiler casing, on top of the control panel.
Connections must only be made using appropriate diameter multi strand flexible cables. Cable entry must
only be via the rubber glanded cable points located at the bottom rear of the appliance: the low voltage
cables are at the left side (top in the drawing below) and the 230 VAC cables are at the right hand side
of the boiler (bottom in the drawing below).
If the boiler is to be room sealed, then care must be taken to ensure the cable entries are reasonably air-tight.
7.2 Boiler Plug & Connector Strip

Heating curve
When an outside temperature sensor has been connected, the boiler will respond to the program of weather
compensation (but not when 0 to 10 volt control is used)
Through the parameter menu the heating curve (see page 20) can be set: to do this, use the parameter menu
with the interface cable together with a laptop and the necessary software.
When the outside temperature sensor is connected, the cable terminals “13” and “14” should be bridged; or
an On/Off control should be used. For RC and E-BUS see separate data.
With the temperature button on the display (CH) this heating curve can be shifted with + and - 5°C.
The default for the heating curve of the main circuit is set to K-factor “3,5” See graph page 20

NOTE :
When a Calorifier is connected, a hot water sensor or an on/off thermostat can be
connected. If a sensor is connected, the domestic hot water is set at 60 in the Boiler
and also the water temperature will be shown on the display when active on DHW.
1.
When no on /off control is connected, the boiler temperature is controlled
by the maximum flow temperature, (set by the CH Control Knob on the
Panel). In this case a link has to be used between 13 and 14 .When an
outside temperature sensor is connected, the boiler is controlled through the
heating curve, which can be shifted with the CH Control knob on the Panel.
2.
When an On/Off Control (with or without a timer) is connected, this
control switches the boiler Off, when the desired temperature reaches the
temperature set on such control. (with or without outside temperature
compensation).
When two or more boilers are connected to the boiler control (every boiler control
has a built in cascade manager) each boiler of the cascade has to be connected to the
next boiler, using a two wire bus (cascade connection) terminals. A Flow
Temperature sensor is also required available at extra cost from Strebel.
The cascade control must be used on multiple Boiler systems sharing the same flue.

8.4 Display console buttons
There are a couple of uses of the buttons and knobs on the display console, namely to adjust settings or to get
information:
-- means the “OFF”
“0” on the display means: “No heat Demand”
On Heat Demand, the required boiler temperature is shown on the Display or domestic water
temperature during DHW demand (DHW if fitted )
8.4.1 Service Button
SERVICE press button.
In order to set the gas-valve for the maximum output as well as for the minimum output, the
appliance has to be put into the SERVICE mode: press a ball pen (or similar) into the small hole
beneath the plastic cap at the right side of the control fascia (see 8.1 page 25).
By turning the CH knob, the speed of the fan can be set between the maximum and minimum speed.
The display will show the speed of the fan e.g. 25 means 2500 r/min.
After 10 min. the boiler switches back to the automatic program: If the setting of the gas-valve is not
complete, press the switch again.
The temperature of all the connected sensors can be shown (without the help of a laptop) on the
display. Press the RESET button, the first temperature is now shown (blinking) together with the
code of the sensor (blinking).
To see the temperature of the next sensor, press again the RESET button.

8.5 Filling and venting the Boiler and the system in preparation for light up.
Fill the central heating boiler and the heating system using the appropriate filling method. The correct fill
pressure is >0.5 bar max 6 bar
Pay attention to the following aspects in order to prevent corrosion of the CH system:
•
•
•
•
Fill water: if desired use X100 (only) additive to the water for the central heating. The pH value
should be higher than 5 (if not, we suggest you contact Strebel).Test the water. Use additive as required
Thoroughly flush out the central heating system removing all traces of flux and debris.
Ensure that any plastic pipes that are being used are oxygen diffusion-proof in accordance with DIN
4726/4729. If not, separate the boiler circuit and the plastic pipes using a plate heat exchanger
Check the circuit for leaks to prevent oxygen from entering the system.
The boiler has an automatic air vent, at the top of the boiler, this must be opened when the boiler is put
into operation. Check that the A/V screw cap is open by at least one twist. Check all system air vents are
open.
Shortly after putting the boiler into operation, check the filling pressure and add more water to maintain the
required pressure, if necessary .Cure any leaks on the heating and dhw system
Page 28 of 51
8.6 Commissioning
8.6.1 General
Measure the gas pressure in the gas pipe at the pressure nipple (3) of the gas safety valve.
The gas pressure needed for the boiler to work properly under full output is a minimum of 15 mbar (or
current regulations, if greater) all plant running.

Once the system has been filled, vented, (see 8.5 page 28) tested and everything is in order according
to this manual, connect the central heating boiler to the mains and turn the boiler on..
Make any external control device. IE room stat, control panel etc
When the boiler is turned on, the display will show the requested water temperature (see 8.4 , 8.4.1 )
The burner control will repeatedly give an electronic spark until a flame appears. If no flame appears
after several attempts, check 1), the gas supply. 2), the gas valve has been set correctly.
The Boiler has a built in hot water control, the boiler will first heat up the calorifier (when connected).
Once the calorifier is hot (if fitted), adjust the room thermostat (or make an external control) to a higher
value to start the burner for CH.
8.7 Adjusting and setting the output or when checking or replacing a new gas control valve
Set the valve via measuring the CO2 percentage (LPG is set by CO see page 40 & 41) and gas consumption
rate (The flue may effect the Boiler output see pages 13, 14 and 15) Use this method to set both the minimum
and the maximum output: first set the maximum output and then set the minimum output.
8.7.1 Setting the maximum output
Press with a ball pen (or similar) the SERVICE button (8.4.1) in the small hole beneath the plastic cap at the
right side of the control fascia and then turn the CH knob to give the maximum fan-speed (See table 4. page
30) Measurement of the emissions and CO2 percentage is via the measuring point in the flue gas pipe, (after
unscrewing the plastic cap).
If necessary, turn the adjusting screw 2 (see Figure 4 above) for setting; either anticlockwise to increase the
CO2 percentage or clockwise to reduce the CO2 percentage (see fig 4 page 30). For setting the minimum
output CO2 percentage see page 31 8.7.2 ( LPG is set by CO see page 40 &41).

8.7.2 Setting the minimum output
Set the minimum load once the maximum load has been set. In service mode turn the CH knob until the
minimum RPM setting has been reached (20 on the display). In order to set or adjust the minimum load, twist
the screw [1] for the minimum setting. Turn the screw clockwise to increase or anti-clockwise to decrease the
CO2 percentage, (see table 4 a page 30). The gas valve on the S-CB150 and S-CB180, you only are allowed
to set the gas valve on the right hand side. DO NOT ADJUST THE LEFT HAND SIDE GAS VALVE
For Gas Valve Adjustment see illustration on page 29 Figure 4
8.8 Gas conversion
Converting from Nat. gas to LPG:
Boilers with a single gas valve: SCB 60 up to 120 kW: See page 40
Boilers with a two gas valves: SCB 150 up to 180 kW: See page 41
NOTE:
Set LPG by CO emission
Setting LPG CO² % is not important, because it is influenced by the quality of the LPG,
which differs quite a lot; mostly the measured CO² % is roughly between 9.5% and 10%.
High Fire CO: is set to less than 100 ppm CO.
Low Fire CO is set to less than 10 ppm .
Page 31 of 51
9. LONG TERM SHUTDOWN
It is recommended to leave the boiler turned on all year round to prevent frost damage in winter and moving
parts seizing due to corrosion during other times of the year. To switch the boiler off break the frost protected
control circuit (by others) or turn the room thermostat down (minimum power consumption is now assured);
the pump for the central heating and the fan will stop after a short delay.
If the boiler has to be put out of operation, the following action must be taken:
•
Close the gas cock.
•
Remove the electrical plug from the wall socket, or switch off the mains-power.
•
In the event of possible frost damage: drain both the boiler and the system.
When draining the boiler, drain the system first. Then open the two drain cocks of the boiler.
•
•
•
Put the O/I switch to position “O” and the On / OFF switch in position “OFF”.
Isolate at local isolation.
Open the filling and drain valve of the central heating system and the boiler drain valve on the right- and
left-hand side of the boiler.

Check cable or replace the cable, check that the cable is connected to the correct connector strip.
Replace room thermostat or cable: has the correct thermostat been used?
Replace sensor or find cable fault.
Try and loosen the pump spindle, or replace the pump drive.
Add water and detect leak, also check the expansion vessel for leaks.
Too much water added; drain, check the pressure in the expansion vessel for correct air cushion
pressure(only check with 0 water pressure) replace the expansion vessel if defective
Place the plug: with the cables on the fan side.
Clean the fan blades.
Replace the fan
Open gas valve.
Check line and gas meter, make a resistance calculation, as required.
Change gas lines.
Check fuse F4- check all 230 V connections: pump, PCB.
See paragraph 6.4
Check the cabling using the wiring diagram, check the connection to the gas valve, be aware of
moister
Check cable for short-circuit, overheating, nearby or jammed between steel plate; check spark
plug cap for cracks, replace cap.
Replace the burner control.
Moister trapped, check the cable sockets which should fit tightly around the plug pins, check the
position of the cable socket, possibly adjust before the plug slides in.
Check that the plug(s) are fitting tightly.
Open the drain line (left-hand side of the boiler) by unscrewing the cap. Keep a jug on hand to
catch the amount of water drained. Poke through the line using a pen, moving left upward and
right upward. Take the burner unit from the boiler as required and pour some water in the heat
exchanger to rinse out the siphon.
Bleed the unit, not only the boiler itself but the entire system – in the event of such overall deaeration it is recommended to remove the 230 V off the boiler from the wall switch as the CH
pump should not be activated during the process.
Check the cut-off valve of the three-way valve. Take the pump motor out by unscrewing the four
fastening screws. Check the valve on the inside of the housing.
The driving motor can be removed by taking out the fastening screw at the front of the housing
(right bottom) and subsequently pressing the “snap in” lug on the side of the housing, just above
the motor, while pressing the motor down at the same time.
Check the air inlet and flue lines for blockage.
Check the inlet and flue system.
See 26.
REPLACE THE BOILER
Replace the high-limit thermostat by unscrewing from the brass nut: no draining is needed (do not
remove the brass nut).
Go over the settings as outlined in paragraph 6.6.1.
Troubleshooting table (cont’d)
34. Remove the burner control from the boiler by:
a. Removing the ignition cable from the electrode and remove the cable from the console
b. Removing the wiring from the spiral – 1X2-pole plug, 1X8-pole plug and the 230V-plug (right
side of the front). Unscrew the facia (4x) remove the burner control and replace it.
35. Replace, when bending: take care as bending near the burner plate may give a risk of cracking.
36. Dry, using a hairdryer as necessary, and check if working. Replace as necessary.
37. See 36.
38. See 36. Remove the connection and blow dry, using a hairdryer.
39. See 36. Remove the connection and blow dry, using a hairdryer.
40. The plug/ wire connection must point to the outside of the fan and one side should fit into the groove
on the PCB.
41. Check plugs and fit into one another correctly.
42. Check cables for possible damage or being trapped, and replace as required.
43. Check connections, or replace sensor.
44. Check the seal of the heat exchanger on the flue gas casing, and replace as required, fit a new rotary
lip seal.
45. Check flow and DHW-Pipes.
46. Turn the pump switch to position 3.
47. Check if the sensors are interchanged.
48. Possibly replace the fuse (must be a reason for the defect); there is no spare fuse present, see
diagram on page 26.
49. Possibly replace fuse (must be a reason for the defect); there is no spare fuse present, see diagram on
page 26.
50. Check the mains lead, the wall box for voltage; main fuse
51. Check the programmed parameters
52. Check the type of room thermostat and the indication on the sticker of the connector strips on the
boiler.
53. Change the pulse width program; see parameter manual.
54. Change the “wake-up” times of the clock thermostat.
55. Flow is on the left-hand side of the boiler; return on the right-hand side.
56. Check three-way valve including cables on the valve as well as on the connection strip.
57. Check the sensor on the calorifier.
60. It may occur that the 18-pin PCB plug moved up one pin too far; this may cause a fault in the
communication between the wiring and the pins: check both the left and the right-hand side of the
PCB plug to make sure the plugs are placed correctly.
61. A defect to the gas block usually has one of two causes: the electric coils are defective, or an internal
defect on the gas valve. In either case it would be recommended to replace the entire gas valve.
63. Use the correct software (please check) for programming. Also, do not exceed the value limits. Try
to reprogram.
64. Check the supply voltage using a universal meter; if the voltage is correct (should be between 190
and 250 Volt) replace the burner control.
65. In order to restore the Reset key, take the display from the plastic spacers and try the proper working
again. If negative, replace the display. If the display works outside the boiler, check that the key has
sufficient space under the plastic cover (not being blocked); make room.
If the letter “H” is not blinking, replace the burner control.
66. Re-adjust the gas valve as per the instructions.

12 INSPECTION AND MAINTENANCE
12.1 General
The boiler requires inspection at least once every 12 months.
As a rule of thumb, inspection/maintenance is to be carried out when the boiler generates a number of similar
error codes.
12.2 Inspection (Items J K L Major Service)
An inspection should cover at least the following matters.
a.
Ask the user about any problems with the CH boiler and/or any comments.
b.
Check the system (water) pressure.
c.
Remove the casing of the boiler and check all lines and connections for traces of water and water
leakage.
d.
Inspect the top of the casing and/or the top of the boiler for water leakage or traces of water from the air
supply pipe or the de-aerator.
e.
Open the condense siphon and remove any dirt.
f.
If a laptop computer is available, connect this computer and check the service page for error messages,
starts and failed / successful starting attempts.
g.
Fire the boiler on maximum output, and measure the output and the CO2 percentage.(CO on LPG)
h.
Fire the boiler on minimum output, and measure the output and the CO2 percentage.(CO on LPG)
i.
Note the noise of the CH pump and the fan.
j.
Dismantle the burner unit: remove the 6 x M6 nuts and the ignition cable, and move the burner unit
forward. Remove the plug of the fan cable to the fan when the burner has been pulled half-way from the
combustion chamber Check the inside of the heat exchanger.
k.
Dismantle the air gas mixing box on the suction side of the fan and check the fan blades.
l.
Check the distance from the electrode to the burner; there should be 4 to 5 mm gap.
Figure 3; Distance from electrode to burner S-CB
Page 38 of 51
12.3 Maintenance
Depending on the outcome of the inspection, (preventative) maintenance should be considered.
Reasons may be:
ref. a.
Comments and notes from the customer should be taken seriously and an effort should be made to
find the cause of any deficiencies and problems.
ref. b.
The pressure of the system should be set between 1 and 6 bar: find possible leaks in the system and
have these fixed.
ref. c.
Any leakage must be repaired.
ref. d.
Flue: Find the cause of any water leakage from the air supply (possible cause from the roof
surface). Check the concentric flue and trace any leaks in the flue gas discharge and rectify.
ref. e.
Rinse if the condensed water from the siphon is badly contaminated. Several options are available.
1.
If the burner has already been removed: using a filling hose, pour water into the heat
exchanger (it will eventually reach the siphon).
2.
Adjust the drain line up (if possible) allowing the water to flow to the drain of the boiler.
ref. f.
Act upon the findings from the service screen using the service program or a laptop computer (if
used). and change any parts that may be the cause of these faults,
ref. g.
See under h.
ref. h.
Adjust the gas setting at the gas safety valve, as necessary, under minimum output.
ref. i.
If the CH pump has become noisy (certainly when the pump has been working for more than five
years) it is recommended to replace the pump motor as a precaution.
ref. j.
Never clean the burner itself it is not required If dirt has built up on the inside of the heat exchanger
and/or scale has formed on the inside of the stainless steel pipes, it should be removed using a hard
brush and citric acid do not use a steel brush! Always vacuum any dirt away.
ref. k.
If deposits have built up on the fan blades, carefully clean the blades one by one until the blades are
clean again. Work consistently in cleaning the blades, or else the fan may run irregularly and get out
of balance.
ref. l.
Carefully bend the electrode until the gap is correct 4 to 5 mm or replace (see page 44)
13 INSTRUCTING THE USER
Show the user how to operate the entire system. Above all, the user should be made familiar with all safety
precautions. The user should be told that service and maintenance of the central heating boiler is required
every 12 months or more. Regular service is essential for the safe operation of the boiler. Hand the user the
documents supplied with the S-CB boiler.

Boilers with a single gas valve: SCB 60 up to 120 kW:
- Converting from Nat. gas to LPG:
1.
2.
3.
Turn the small "throttle"(see page 29) screw 2 clockwise about nr. 4 half turns.
press the service switch (with a pen).
The appliance should start: when there is no ignition, open the throttle 2 (anti - clockwise) with
about another half turn.
4. Turn the red control knob on the control panel to the maximum -the speed of the fan will go to
maximum: the colour of the flame should be blue: if yellow, give a little less gas (throttle
clockwise, or when the flame disappears, anti- clockwise).
5. When the flame has the right colour: place the analyser in the measuring hole of the tube not before,
otherwise you could get too much CO in the analyser .
6. Set the throttle screw 2to obtain a reading of about 100 ppm CO Note CO² % is not important it will
be around 9,5 %.
7. Turn the red control knob on the control panel to the left to about 9 O’Clock.
8. Set the screw 2 to obtain about 50 ppm CO.
9. Turn the red control knob on the control panel to the minimum.
10. Set the screw 1 so the analyser shows a CO value lower than 10ppm.
11. Turn the red control knob on the control panel to the maximum, to check the max. CO value, reset
(if required) the CO to less than 100 ppm with help of the Throttle screw.
When fitting a new gas valve:
1. Open the throttle (see page 29) screw 2 (anti - clockwise) completely; then turn screw 8 half turns
clock wise.
2. Press the service switch (with a pen).

Open the throttle screw (anti - clockwise) completely; then turn the screw 8 half turns clock wise.
Press the service switch (with a pen) .
Commission the valves as per the commissioning instructions above starting at no 3
Conclusion
Set the Boiler on CO emission
Setting LPG CO² % is not important, because it is influenced by the quality of the
LPG, which differs quite a lot; mostly the measured CO² % is about between 9,5 and
10%) High Fire CO: less than 100 ppm Low Fire CO less than 10 ppm.
